Cathode is a reducing electrode because :

1. it has less number of electrons

2. it has deficiency of electrons

3. cations gain electrons from cathode

4. anions lose electrons to cathode

Which statement about conduction of electricity is correct?

1. Electricity is conducted in an aqueous solution by electrons.

2. Electricity is conducted in a metal wire by ions.

3. Electricity is conducted in a molten electrolyte by electrons.

4. Electricity is conducted in an acidic solution by ions.

During electrolysis, what happens to metallic ions and at which electrode do they get discharged ?

P Reduction of metallic ions, cathode

Q Oxidation of metallic ions, anode

R Oxidation of metallic ions, cathode

1. Only P

2. Only Q

3. both P and Q

4. Both Q and R

Assertion (A): Electrolysis establishes a relationship between electrical energy and chemical energy.

Reason (R): Substances like metals, carbon (graphite) are conductors while salts like NaCl, KCI are electrolytes.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.
